1: Daze in the Valley by Jay Cantrell I just reread this again, for the 3rd or 4th time. It's an interesting (fictional) take on the adult movie industry, that never fails to arouse.
2: For Want of a Memory by Lubrican I could list every one of Lubrican's stories here, but I'll single this one out. He's a legendary author and for good reason. I don't think anybody does as well as he can in terms of pacing and building desire in his characters. I also happen to have a massive literary crush on his character Lulu.
3: Time of Eden and Elves by Mike Cropo If Oil of Roses is epic. This story is mega-epic. Action adventure/military sci-fi with a lot of hot sex thrown in. I was riveted. And then I discovered this was only Book 1 of 5! I must've lost 2 weeks to non-stop reading of this series, and it was totally worth it.
4: Tired of Being the Nice Guy by MWTB Classic, funny, and hot. This is one of the first BDSM stories I'd ever read. I still come back and read it from time to time for fun.
